4 Ways to Prevent Mold Cross-Contamination
Once mold is present in a building, cross-contamination is likely to occur unless you take preventative measures. There are four methods that building owners and mold cleanup experts can use to stop cross-contamination.
1. Turn Off the HVAC System
Ventilation can reduce the likelihood of mold by drying out moisture, but fans or an HVAC system can also spread spores throughout a structure. Turn off ventilation systems as soon as you smell a moldy odor, see visible fungus, or suspect that hidden mold may be present.
2. Use Plastic Materials for Limited Containment
A building owner or cleanup professional can seal off 10 to 100 square feet of mold contamination with polyethylene sheeting or other plastic materials. Mold cleanup professionals can set up these barriers quickly and properly to prevent mold spores from spreading.
3. Seal Off Openings
It is also important to seal off openings such as air supplies, doors, pipe chases, or vents. It is a good idea to restrict traffic on the part of occupants or workers to prevent contaminated air from escaping from the affected area. You may want to use a dehumidifier to lower moisture levels and make other parts of a structure less hospitable for mold.
4. Create a Negative Air Chamber
If mold growth is extensive, cleanup professionals may assemble an airtight containment area that produces negative air pressure. This installation is created with plastic barriers and double layers of polyethylene sheeting. Depending on the severity of the mold, a decontamination chamber may also be necessary to prevent workers from spreading it to other parts of the structure.
Property owners can turn off HVAC systems and attempt to seal off doors or vents, but mold contamination mitigation professionals are skilled at setting up containment zones and negative air chambers. A consultation with a commercial mold cleanup service in Nelson, GA may be in order if you suspect a mold problem.
